This book discusses the notion that quantum gravity may represent the "breakdown" of spacetime at extremely high energy scales. If spacetime does not exist at the fundamental level, then it has to be considered "emergent", in other words an effective structure, valid at low energy scales. The author develops a conception of emergence appropriate to effective theories in physics, and shows how it applies (or could apply) in various approaches to quantum gravity, including condensed matter approaches, discrete approaches, and loop (...) quantum gravity.

In times of crisis, when current theories are revealed as inadequate to task, and new physics is thought to be required—physics turns to re-evaluate its principles, and to seek new ones. This paper explores the various types, and roles of principles that feature in the problem of quantum gravity as a current crisis in physics. I illustrate the diversity of the principles being appealed to, and show that principles serve in a variety of roles in all stages of the crisis, (...) including in motivating the need for a new theory, and defining what this theory should be like. In particular, I consider: the generalised correspondence principle, UV-completion, background independence, and the holographic principle. I also explore how the current crisis fits with Friedman’s view on the roles of principles in revolutionary theory-change, finding that while many key aspects of this view are not represented in quantum gravity, the view could potentially offer a useful diagnostic, and prescriptive strategy. This paper is intended to be relatively non-technical, and to bring some of the philosophical issues from the search for quantum gravity to a more general philosophical audience interested in the roles of principles in scientific theory-change.

Analogue experiments have attracted interest for their potential to shed light on inaccessible domains. For instance, ‘dumb holes’ in fluids and Bose–Einstein condensates, as analogues of black holes, have been promoted as means of confirming the existence of Hawking radiation in real black holes. We compare analogue experiments with other cases of experiment and simulation in physics. We argue—contra recent claims in the philosophical literature—that analogue experiments are not capable of confirming the existence of particular phenomena in inaccessible target systems. (...) As they must assume the physical adequacy of the modelling framework used to describe the inaccessible target system, arguments to the conclusion that analogue experiments can yield confirmation for phenomena in those target systems, such as Hawking radiation in black holes, beg the question.

Principles are central to physical reasoning, particularly in the search for a theory of quantum gravity, where novel empirical data are lacking. One principle widely adopted in the search for QG is ultraviolet completion: the idea that a theory should hold up to all possible high energies. We argue— contra standard scientific practice—that UV-completion is poorly motivated as a guiding principle in theory-construction, and cannot be used as a criterion of theory-justification in the search for QG. For this, we explore (...) the reasons for expecting, or desiring, a UV-complete theory, as well as analyse how UV-completion is used, and how it should be used, in various specific approaches to QG. 1Introduction 1.1Principles in theory development and evaluation 2Primer on UV-Completion, Renormalizability, and All That 2.1Renormalizability and UV-completion 2.2Other forms of UV-completion 3Why Should QG Be UV-Complete? 3.1UV-completion and fundamentality 3.2UV-completion and minimal length 4UV-Completion in Different Approaches to QG 4.1String theory 4.2Asymptotic safety 4.3Causal dynamical triangulation 4.4Higher derivative approaches 4.5Supergravity 4.6Causal set theory 4.7Canonical QG 4.8Loop quantum gravity 4.9Approaches based on alternative gravitational theories 4.10Emergent gravity approaches 5UV-Completion as a Guiding Principle in QG 6Conclusion.

The classic Lewis-Stalnaker semantics for counterfactuals captures that Sobel sequences are consistent sequences, for example: a.If Sophie had gone to the parade, she would have seen Pedro dance. b.But if Sophie had gone to the parade and been stuck behind someone tall, she would not have seen Pedro dance. But reverse a sequence like this one and it no longer sounds so good, which is surprising on the classic semantics. This observation motivated Kai von Fintel and Thony Gillies to propose (...) dynamic semantic accounts of counterfactual conditionals. Subsequently, Sarah Moss defended the classic semantics against the charge that it need be abandoned in the face of these order effects, arguing that the infelicity of the reverse sequences is pragmatic. I argue that both accounts are ultimately untenable, but each account has strengths. Seeing what works and what doesn't in each account points the way to the right positive view. With this in mind, I defend a contextualist account of counterfactuals that takes conversational relevance to play a central role. (shrink)

The numerous and diverse roles of theory reduction in science have been insufficiently explored in the philosophy literature on reduction. Part of the reason for this has been a lack of attention paid to reduction2 (successional reduction)—although I here argue that this sense of reduction is closer to reduction1 (explanatory reduction) than is commonly recognised, and I use an account of reduction that is neutral between the two. This paper draws attention to the utility—and incredible versatility—of theory reduction. A non-exhaustive (...) list of various applications of reduction in science is presented, some of which are drawn from a particular case-study, being the current search for a new theory of fundamental physics. This case-study is especially interesting because it employs both senses of reduction at once, and because of the huge weight being put on reduction by the different research groups involved; additionally, it presents some unique uses for reduction—revealing, I argue, the fact that reduction can be of specialised and unexpected service in particular scientific cases. The paper makes two other general findings: that the functions of reduction that are typically assumed to characterise the different forms of the relation may instead be understood as secondary consequences of some other roles; and that most of the roles that reduction plays in science can actually also be fulfilled by a weaker relation than (the typical understanding of) reduction.

Despite the fact that the High-Church Tory, Mary Astell, held political views diametrically opposed to the Whiggish Catharine Trotter Cockburn and Catharine Macaulay, it is here argued that their metaethical views were surprisingly similar. All were influenced by a blend of Christian universalism and Aristotelian eudaimonism, which accepted the existence of a law of nature, that we strive for happiness, and that happiness results from living in accord with our God-given nature. They differed with regard to epistemological issues; the means (...) by which we can know the law of nature, and with regard to the characterization of that nature; our telos. Traces of the ethical theories developed by these women can also be seen in the works of the philosophically informed novelists, Sarah Fielding, Jane Collier, Sarah Scott, and Hannah More. (shrink)

In her paper, 'Two distinctions in goodness', Korsgaard points out that while a contrast is often drawn between intrinsic and instrumental value there are really two distinctions to be drawn here. One is the distinction between intrinsic and extrinsic value, the other is that between having value as an end and having value as a means. In this paper I apply this contrast to some issues in environmental philosophy. It has become a commonplace of environmentalism that there are intrinsic values (...) in nature. What is usually meant by this is that some values in nature are not merely instrumental to human ends. By using the notion of intrinsic value to express this philosophers have developed positions which are open to a number of meta-ethical and practical objections. The view that there are objective values in nature, which are independent of human interests, is better served by an environmental philosophy which sees most value in nature as objective, extrinsic value. The resulting environmental ethic is sketched and some apparent difficulties discussed. (shrink)

Dummett's output has been prolific and highly influential, but not always as accessible as it deserves to be. This book sets out to rectify this situation.

Argues that like more conservative feminist writers, Gabrielle Suchon and Mary Astell, writing earlier in the Eighteenth Century, Macaulay's concept of liberty is closely tied to virtue and involves free self government according to reason. Unlike these earlier writers from this concept of liberty she deduces the rationality of democratic republican government. Thus the grounds on which she builds her republicanism involve a very different concept of rational self interest to that usually assumed to ground social contract theory. For virtue (...) and the genuine self interest of rational beings are taken to coincide. (shrink)

This is a timely re-appraisal of feminist political thinkers and their male contemporaries, providing a re-evaluation of feminist humanism.

Within physics there are two ways of establishing the relative fundamentality of one theory compared to another, via two senses of reduction: "inter-level" and "intra-level" (Crowther, 2018). The former is standardly recognised as roughly correlating with the chain of ontological dependence (i.e., the phenomena described by theories of macro-physics are typically supposed to be ontologically dependent on the entities/behaviour described by theories of micro-physics), and thus has been of interest to naturalised metaphysics. The latter, though, has not been considered interesting (...) for metaphysics, because it is not thought to correlate either with ontological dependence, nor causal or dynamical dependence. I argue, however, that this is a mistake, and that actually, the intra-level relation does reflect ontological dependence (in the same sense as the inter-level relation) and thus should not be neglected by metaphysics of physics. This argument further supports the assertion that the same notion of fundamentality underlies both the inter- and intra-level claims of fundamentality in physics, and that this notion of relative fundamentality in physics correlates with that of metaphysics.

Singularities in general relativity and quantum field theory are often taken not only to motivate the search for a more-fundamental theory (quantum gravity, QG), but also to characterise this new theory and shape expectations of what it is to achieve. Here, we first evaluate how particular types of singularities may suggest an incompleteness of current theories. We then classify four different 'attitudes' towards singularities in the search for QG, and show, through examples in the physics literature, that these lead to (...) different scenarios for the new theory. Two of the attitudes prompt singularity resolution, but only one suggests the need for a theory of QG. Rather than evaluate the different attitudes, we close with some suggestions of factors that influence the choice between them. (shrink)

Introduction for the Synthese Special Issue on Spacetime Functionalism.

Current discussion of scientific realism and antirealism often cites Pierre Duhem’s argument for the underdetermination of theory choice by evidence. Participants draw on an account of his underdetermination thesis that is familiar, but incomplete. The purpose of this article is to complete the familiar account. I argue that a closer look at Duhem’s The aim and structure of physical theory suggests that the rationale for his underdetermination thesis comes from his philosophy of scientific language. I explore how an understanding of (...) physical laws as symbolic is meant to support the thesis. In the course of my argument, I point out that Duhemian underdetermination is not meta-practical but grounded in the practice of science, specifically in the scientist’s use of instruments and measurement techniques. Measurement has a significant limitation, according to Duhem: it always involves approximation and a degree of experimental error. Consequently, it cannot overcome the gap between the ordinary, concrete language of observation and the mathematical language of science. Moreover, Duhem argues that the use of instruments in experiment invokes whole groups of theories. I contend that, ultimately, this reliance on auxiliary assumptions—which makes possible the use of instruments—is the foundation of his thesis and that recognizing this completes the familiar account of his underdetermination argument.Author Keywords: Duhem; Suppes; Underdetermination; Measurement; Physical theory.

The interventionist account of causation has been largely dismissed as a serious candidate for application in physics. This dismissal is related to the problematic assumption that physical causation is entirely a matter of dynamical evolution. In this article, I offer a fresh look at the interventionist account of causation and its applicability to thermodynamics. I argue that the interventionist account of causation is the account of causation that most appropriately characterizes the theoretical structure and phenomenal behavior of thermodynamics.

Self-tracking practices include the use of personal data-gathering apps, wearable devices, and data analysis tools to record patterns from daily activities, as well as the organization, visualization, and analysis of this data. This paper draws on theories of digital labour and feminist political economy to build a framework of digital productive labour that highlights the exploitation of activities external to the formal labour relationship. Self-tracking practices are analysed through the lens of digital productive insofar as they fulfill three roles: they (...) generate the content necessary for sustaining digital networks and producing data that can be captured in commodity form; they aid in the reproduction of the social factory’s labour force; and they cultivate subjectivities amenable to consumption and production in contemporary capitalism. The paper examines the production and commodification of data, highlighting the algorithmic means by which self-trackers are separated from the financial value of their data. This is connected to feminist analyses of unpaid labour, with particular attention to self-tracking’s role as a contemporary form of reproductive labour that replenishes the labour force. Finally, the paper provides an analysis of the themes of self-knowledge, self-discovery, and gamification to understand how these frame self-trackers’ understanding of themselves as labourers, thus reproducing and deepening capitalist subjectivities. The paper concludes by considering self-tracking through the lens of the exploitation of life ‘outside’ the official labour relationship. (shrink)

Despite its importance for early analytic philosophy, Gottlob Frege's account of existence statements, according to which they classify concepts, has been thought to succumb to a number of well-worn criticisms. This article does two things. First, it argues that, by remaining faithful to the letter of Frege's claim that concepts are functions, the Fregean account can be saved from many of the standard criticisms. Second, it examines the problem that Frege's account fails to generalize to cases which involve definite descriptions (...) and proper names. To deal with this the proffered analysis deviates from the letter of Frege's views, while remaining within its spirit. It proposes, in opposition to Frege, that expressions which grammatically look like singular terms should not always be read as referring to objects, but are sometimes best analysed as indicating functions.

Objections are raised to the demand that one be either exclusively for or against continental philosophy, and two arguments are developed; one in support of, and one against, positions developed within the continental tradition. The first is a quick argument against A.J. Ayer’s rejection, on the basis of Frege’s logical insights, of Heidegger and Sartre’s use of ‘nothing’. The second is a longer argument against Derrida’s claim, on the basis of his critique of Husserl’s phenomenology, that the difference between signifier (...) and signified is nothing. The second argument develops an exposition of Derrida’s critique of phenomenology, from the point of view of language, and argues, on the basis of that reading, that his claim is either banal or highly implausible.

I. Logic, rationality and ideology Herbert Marcuse once claimed that the ‘“rational” is a mode of thought and action which is geared to reduce ignorance, destruction, brutality, and oppression.’ He echoed a widespread folk belief that a world in which people were rational would be a better world. This could be taken as an optimistic empirical conjecture: if people were more rational then probably the world would be a better place (a trust that ‘virtue will be rewarded’, so to speak). (...) However, it is also worth considering a stronger hypothesis: that if something did not reduce ignorance, destruction, brutality, and oppression then it would not constitute rationality. On this view there is no mere correlation between rationality and a propensity toward reduction in ignorance and the rest, it is the propensity to reduce ignorance, destruction, brutality and oppression which in part constitutes rationality. Call this a broad conception of rationality, because it expands beyond the epistemic goal of reducing ignorance, and reaches out to moral concerns like oppression. (shrink)

In this paper I distinguish normative and descriptive reasons for attempting to construct a logic for belief sentences, and argue that because the interpretation of the content of an attribution of belief is context sensitive and ambiguous, no simple logic is adequate.

The general conceit of Schiller’s aesthetic education is that our experiences with art and beauty set us free from internal and external constraints and allow us to embrace our full humanity as rational and sensuous beings. Experiencing the aesthetic, or the play impulse, puts one in a state of aesthetic determinacy—or rather indeterminacy—that Schiller calls the highest sense of freedom, aesthetic freedom. Gail K. Hart examines Anthony Burgess’s A Clockwork Orange as an example of what Schillerian aesthetic education might look (...) like in practice. Though it represents a distortion of Schiller’s aesthetic education, Hart argues that it also reveals an ineradicable element of coercion in aesthetic education. I argue that Burgess’s Ludovico Technique leaves out a key element of Schiller’s conception of aesthetic cultivation—play—and that Hart’s analysis of Schiller’s work likewise lacks a robust analysis of his notion of play. I argue that, when Schiller’s account of the play impulse is taken seriously as a necessary condition for aesthetic cultivation to take place, coercion is by definition made impossible. Aesthetic play is accomplished by the mutual destruction of physical and moral determinations, and this mutual erasure leads to a higher and more expansive freedom. External constraints and coercion cannot induce the aesthetic state, so aesthetic education as Schiller presents it in On the Aesthetic Education of Man cannot contain the element of coercion Hart suspects.

This article explores the processes through which Australian recipients select unknown donors for use in assisted reproductive technologies and speculates on how those processes may affect the future life of the donor-conceived person. I will suggest that trust is an integral part of the exchange between donors, recipients, and gamete agencies in donor conception and heavily informs concepts of relatedness, race, ethnicity, kinship, class, and visibility. The decision to be transparent about a child’s genetic parentage affects recipient parents’ choices of (...) donor, about who is allowed to “know” children’s genetic backgrounds, and how important it is to be able to “pass” as an unassisted conception. In this way, recipients must trust the process, institutions, and individuals involved in their treatment, as well as place trust in the future they imagine for their child. The current market for donor gametes reproduces normative conceptions of the nuclear family, kinship, and relatedness by facilitating “matching” donors to recipients by phenotype and cultural affinities. Recipient parents who choose not to prioritize “matching,” and actively disclose the process of children’s conceptions, may embark on a project of queering heteronormative family structures and place great trust in both their own children and changing social attitudes to reduce stigma and generate acceptance for non-traditional families.

This paper explores two phases of the early modern genre wars. The first was fought by Marie de Gournay, in her “Preface” to Montaigne's Essays, on behalf of her adoptive father and in defense of his naked and masculine prose. The second was fought half a century later by Nicholas Boileau in opposition to Gournay's feminizing successor, Madeleine de Scudéry. In this debate Gournay's position is egalitarian, whereas Scudéry's approximates to a feminism of difference. It is claimed that both female (...) protagonists in this early debate occlude the female body. The far more sexually explicit prose of Mary Delarivier Manley is then used to raise the question: is it genre, or is it, rather, the very nature of erotic sexuality, that makes it so difficult for women to masterfully expose themselves as authoritative subjects?

In this paper I briefly set out Susan Moller Okin’s liberal feminist position and then rehearse a number of criticisms of Okin which together suggest that dismantling the gender system and adopting the principle of androgyny would not be compatible with liberalism. This incompatibility appears to vindicate an extreme feminist critique of liberalism. I argue that nevertheless a liberal feminism is possible. The liberal feminist ought to adopt the principle of parity, that is, guaranteed equal representation of both sexes in (...) parliament, rather than the requirement of androgyny. Parity follows from a conception of procedural justice, for it provides a mechanism which guarantees that the interests of both sexes are fairly represented in the legislature. Parity may also go some way to alleviating the tensions which exist between feminism and multiculturalism. (shrink)

The Court of Justice of the European Union and the way in which it works can be seen as a microcosm of how a multilingual, multicultural supranationalisation process and legal order can be constructed—the Court is a microcosm of the EU as a whole and in particular of EU law. The multilingual jurisprudence produced by the CJEU is necessarily shaped by the dynamics within that institution and by the ‘cultural compromises’ at play in the production process. The resultant texts, which (...) make up that jurisprudence, are hybrid in nature and inherently approximate. On the one hand, that approximation can lead to discrepancies between language versions of the Court’s case law and thus jeopardise the uniform application of EU law. On the other hand, that approximation and hybridity define EU law as a distinct, supranational legal order. This paper analyses the operation of the CJEU and considers whether a linguistic cultural compromise exists within that institution which exercises a formative influence on the character of its ‘output’—i.e. its jurisprudence—and what that may mean for our understanding of the development of EU law.

The welfare mother is a powerful symbol of the supposed irresponsible, sexually promiscuous, and immoral behavior of the poor. Resting on dominant ideologies of race, class, and gender, the welfare mother suggests not a poor mother but a bad mother. Based on interviews with 34 mothers receiving public assistance, this article explores how women receiving assistance claim for themselves an identity as good mothers by defining the appropriate responsibilities of mothers to prioritize, protect, discipline, provide for, and spend time with (...) their children. The material realities of poverty combined with work requirements now attached to public assistance exacerbate contradictions between these roles and create difficulties for these mothers. This article explores these contradictions and examines the possibilities for and limits of their use as resistance strategies. (shrink)

Bauer, Taub, and Parsi's review of an international sample of standards on informed consent, confidentiality, commercialization, and quality of research in tissue banking reveals that no clear national or international consensus exists for these issues. The authors' response to the lack of uniformity in the meaning, scope, and ethical significance of the policies they examined is to call for the creation of uniform ethical guidelines. This raises questions about whether harmonization should consist of voluntary international standards or international regulations that (...) include an official oversight mechanism and sanctions for noncompliance, and about who should participate in the harmonization process. Moreover, the normative assumptions and political dynamics that shape global policymaking need to be addressed. This commentary explores the policy implications and normative questions raised by the idea of international ethical guidelines for the use of biotechnologies and biotechnological resources such as stored samples of human tissue.

In his late fragment, ‘Sources of Knowledge of Mathematics and Natural Sciences’ Frege laments the tendency to confuse functions with objects and says, ‘It is here that the tendency of language by its use of the definite article to stamp as an object what is a function and hence a non-object, proves itself to be the source of inaccurate and misleading expressions and also of errors of thought. Probably most of the impurities that contaminate the logical source of knowledge have (...) their origins in this.’ This paper applies Frege’s logical insights to a series of influential modal arguments for the existence of souls or minds, in order to demonstrate that they hinge on the error of treating functions as objects. Related arguments have also resulted in the claim that identity statements are necessary, and that apparent identities ‘really’ involve relations of constitution. Here it is argued that once we recognise that all these arguments involve the assimilation of objects and concepts (which Frege identifies with functions) they can be seen to be defective. (shrink)

The case law of the Court of Justice of the European Union is shaped by the language in which it is drafted—i.e. French. However, because French is rarely the mother tongue of those drafting that case law, the texts produced are often stilted and awkward. In addition, those drafting such case law are constrained in their use of language and style of writing. These factors have led to the development of a ‘Court French’ which necessarily shapes the case law produced (...) and has implications for its development, particularly insofar as it inevitably leads to a type of precedent in that case law. That case law also undergoes many permutations of translation into and out of up to 23 different languages. The resultant texts that make up the case law are hybrid in nature—consisting of a blend of cultural and linguistic patterns, constrained by a rigid formulistic drafting style and put through many permutations of translation. The present paper investigates the production of the Court’s multilingual case law and considers whether the hybrid nature of that case law can actually aid the presentation of a ‘uniform’ EU case law.

Dummettian anti-realism–the refusal to endorse bivalence–is generally thought to be associated with idealism This paper argues that this is only true of the position developed by early Dummett. In a later manifestation Dummettian anti-realism is better thought of as providing the logic for anti-realisms of an error theoretic kind. Early on Dummett distinguished deep from shallow arguments for giving up bivalence: deep arguments followed a strong ‘sufficiency’ reading of Frege’s context principle, and made the sentence the primary vehicle of meaning. (...) Enriched by an account of truth in terms of verifiability, deep arguments implied a form of linguistic idealism. From within a perspective that had already made ontology relative to theory, it was natural for the difference between realism and idealism to hinge on the notion of truth for sentences. Having given up the distinction between deep and shallow arguments against bivalence, Dummett, post 1990, asserts that every rejection of bivalence leads to a form of anti-realism. In the intervening years, he has also come to cast doubt on the sufficiency reading of the context principle, particularly as developed by Crispin Wright. These doubts open the space for some more simple-minded criticisms of this strong version of the context principle, developed in the paper. Once the sufficiency reading of the context principle is given up, arguments for failing to assert bivalence come to hinge on beliefs about ‘genuine’ existence. These forms of anti-realism cannot be taken to imply idealism. Rather, in many cases they will be the expression of views of an error-theoretic kind, that are quite compatible with a thorough-going rejection of idealism. (shrink)

Several approaches to developing a theory of quantum gravity suggest that spacetime—as described by general relativity—is not fundamental. Instead, spacetime is supposed to be explained by reference to the relations between more fundamental entities, analogous to `atoms' of spacetime, which themselves are not (fully) spatiotemporal. Such a case may be understood as emergence of \textit{content}: a `hierarchical' case of emergence, where spacetime emerges at a `higher', or less-fundamental, level than its `lower-level' non-spatiotempral basis. But quantum gravity cosmology also presents us (...) with the possibility of emergence of \textit{context}: where spacetime emerges from some `prior' non-spatiotemporal state (replacing the Big Bang), due to particular conditions in the early universe. I present a general conception of emergence which is plausibly able to accommodate both pictures. This is a positive conception that does not rely on a failure of reduction or explanation in any sense (indeed, reduction is a necessary feature of quantum gravity, and is useful in understanding emergence in this case). I also consider the possibility that the distinction between content- and context- based explanations is blurred, or usefully `collapsed', in the case of spacetime emergence. (shrink)
